SNOW-PLOW, SWEEPER, SCRAPER, AND SPRINKLER FOR CAR-TRACKS.

SPECIFICATION forming part of Letters Patent No. 573,511, datedDeeember22, 1896.

Application led October 31, 1895. Serial No. 567,473. (No model.)

To all whom, it may concern.'

Be it known that I, WILLIAM GEUNow, J r., a citizen of the UnitedStates, and a resident of Bridgeport, in the county of Fairfield andState of Connecticut, have invented certain new and useful Improvementsin Snow-Plows, Sweepers, Scrapers, and Sprinklers for Car- Tracks, ofwhich the following is a specification reference being had to theaccompanying drawings, forming a part thereof, in which similar lettersof reference indicate corresponding parts.

)Iy presentinvention relates to improvements in trucks, comprising asnow-plow, a sweeper, a scraper, and a sprinkler, adapted particularlyfor car-tracks; and its object is to provide asimple construction andarrangement of parts which can be easily adapted for operation.

My invention consists of the peculiar construction and arrangement ofparts and combination of devices hereinafter fully and particularlypointed out and claimed.

In the accompanying drawings, Figure lis a side elevation of a truckembodying my improvements. Fig. 2 is a bottom plan view. Fig. 3 is aside elevation showing a snowplow substituted for the brushes andsprinkling devices. Fig. 4 is a top plan view of the construction shownin Fig. 3. Fig. 5 is a sectional view on the line a: x of Fig. 4. Fig. 6is a bottom plan view of the water-tank and its connections. Fig. 7 is alongitudinal sec'- tional view showing the manner in which the truck maybe turned around. Fig. 8 illustrates a side wing adapted to throw thesnow away from the tracks. Fig. 9 is a detail view. Fig. lO is a topplan view of a sweeping device whichI employ. Fig. 11 is a sideelevation of one brush-wheel and showing in dotted lines how the hoodmay be adjusted, and Fig. 12 is a transverse sectional view.

In the practice of my invention I employ a truck comprising aplatform A,screwed upon the side pieces a, which are supported upon the axles a ofthe wheels a2. This truck may be of any suitable size and shape and itis provided with a post B', having a socket b, adapted to receive acoupling-link h', by means of which the truck is connected to a car orother means of locomotion.

On each side of the platform and between the wheels are located thesand-hoppers C, and the valves in the lower parts of the hoppers areoperated by the levers c, and this feature, as well as the scrapers D,are supported on arms d, secured to a rock-shaft d', form no part of thepresent invention, and I will not therefore describe them moreparticularly.

A water-tank E is supported in the platform by the posts e, which areprovided with reduced ends and inserted in holes in the platform; but Imay provide sockets c' on the platform to receive the parts, if desired,as shown in Fig. 9, and secure them therein by means of set-screws. Apipe F leads down from the tank, and it extends forward and is branchedto supply two hub-sprinklers f or a curved perforated pipe. (Not shown.)The branches f are supported from the truck by the arms f2. Aslide-valve G is arranged below the tank in the said pipe, and it isoperated by a lever g and connecting-rod g. A guard-rail II may bearranged on the truckplatform, and a similarrail 71, and a platform hmay be provided for the tank.

On the forward axle a' I secure loosely two forwardly-extendin gsupportin g-bars I,which carry a shaft i in their forward ends. On theend of this shaft i are brush-wheels t', and the brushes are preventedfrom throwing dirt on the sprinkling devices, dac., by means of hoods 2,adjustably secured on the shaft i by means of set-screws i3. The bars Iand the shaft i constitute in themselves a supplemental movable framewhich is preferably secured upon the journal-boxes of the forward axle,and this frame secures the brushes and In order to supports thesprinkling devices. raise or lower this supplemental frame, I provide ahand-screw J, operating in a shoulder j on the support j against arearward and upward projection jz on a supplemental frame. By this meansthe said frame may be raised by operating the screw to force the saidprojection downward, and by turning the screw in the opposite directionthe frame is lowered. On account of this movement of the supplementalframe the pipe F is preferably of some flexible material.

I secure a pulley-wheel K on the shaft and l a larger pulley-wheel k onthe axle a', and connect these wheels by a belt 7c', which is twisted tocause the brushes to revolve in a reverse direction to that of thewheels d2. The pulley wheel 7; is made in two parts and clamps on theaxle by means of set-screws. This pulley-wheel also has an enlarged hubL, provided with recesses and projections adapted to engagecorresponding recesses and projections on a sleeve Z, [ixed on the axlea' and thrown into and out of contact with said hub by means of a leverZ', operating in a grooved wheel Z2. It will thus be observed that whenthe hub and sleeve have been brought into contact to form a clutch, thesleeve being fastened to the axle and the hub L loose thereon, thepulley-wheels 7s K are thrown into operation and the brushes caused torevolve in a reverse direction to the revolution of the wheels a2.'

Under the forward end of the truck I arrange a jack-screw M, which isadapted to be operated to raise the truck from the ground and the wheelsa2 from contact with the rails, so that the truck may be easily turnedaround, and to facilitate this turning of the truck I provide in therear end thereof two wheels m, supported on pivoted arms m. Above thesearms are adj Listing-screws N, which operate in sockets nin the truckand bear against the arms. lVhen these screws are screwed down, the rearend of the truck is raised upon the wheels, and it may be then turnedaround withthe jack-screw for a center. To facilitate this turning ofthe truck, I may provide the rim of the wheels with holes n' to receivea bar or lever. This operation is clearly indicated in Fig. 7 of thedrawings.

It is obvious that the sweeping and sprinkling apparatus, or either ofthem, maybe removed, and they are constructed and arranged with this endin view. Vhen these parts are removed, as, for instance, in the winterseason or during a snow-storm, I Secure in the forward end of the trucka frame comprising a shaft O, arranged at an angle to the axle a', andan arm o, supporting the forward end of the shaft. This shaft is adaptedto rock in its bearings, and it supports a snow-plow 0', which is madeof curved boileriron, as shown. A lever P is connected to saidrock-shaft, and it may be adjusted in position by means of a pin securedin one of the holes in an upright p. By simply operating this lever thesnow-plow can be lowered or raised at will.

In order to throw the snow as far away from the truck as convenient, Iprovide on each side of the truck a side wing Q, which is pivoted to thetruck and is connected bya rod g to a lever g', which may be adjusted ona bar q2. These wings may be thrown out to force the snow away from Athesides of the tracks or folded in close to the truck.

The operation of my improved machine is obvious from the foregoingdescription, and I will not enter into a further elaboration there- Thebrush-frame in said Figs. l0, l1, and 12 i comprises two arms A', whichare preferably secured at the rear ends thereof on the axle or shaft a',and one or both of these arms may be provided with an extension a3, bymeans of which the frame can be raised or lowered. These arms areconnected by two braces a4.

A shaft B' is supported in the forward ends of these arms, and itcarries the brush-wheels i', of some preferred construction, on itsends. This shaft carries a pulley-wheel b2, which is geared with anotherpulley-wheel (not shown) on the axle, by which means the brush-wheelsare driven.

rIhe hoods c4 are preferably made of metal, and they comprise a side C3and a curved top piece c2, the forward end of the hood being inclinedoutwardly and away from the truck. Each hood is provided with a shorthub D', which fits snugly ona collar d4, carried bythe arm A', so thatsaid hoods will remain stationary while the shaft and wheels revolve. Inorder to adjust the hoods at the proper angle to accomplish the bestresults, I provide a setscrew (Z2, by means of which said hoods aresecured in place after they are adjusted.

In the practical operation of my improved device the brush-shaft 'L' isdriven in the reverse direction to the revolution of the carrying-wheelson the truck. The hoods are properly adjusted so that the dirt will bethrown away from the truck, and then the setscrews are fastened.V By thepeculiar construction of these hoods it will be observed that the dirtis directed away from the truck and to one side of the wheels or tracks.

I am aware that many changes in the form and proportion of parts anddetails of construction of my invention may be made without departingfrom the spirit or sacrificing the advantages of the invention, andItherefore reserve the right to make all such changes as fall within thescope of the invention.

Having thus fully described the invention, what I claim, and desire tosecure by Letters Paten-t, is-

l. The combination with a truck, of arms pivotally secured on the rearend thereof and carrying wheels on their free ends, the rim of saidwheels being provided with a series of holes, the sockets n of thetruck-adjusting screws operating through said sockets and bearing on thepivoted arms to raise the rear end of the truck, and a jack-screwsupported under the forward end of the truck and adapted to raise thesame, whereby the truck may be turned around with the jack-screw for acenter, substantially as shown and described.
